The Shape of Life

Documentary that uses scientific investigation and discovery to chronicle the dramatic rise of the animal kingdom. By exploring the major body plans upon which virtually all animal life is built, the program seeks to answer fundamental questions of animal behavior, body design and evolution. Working with renowned scientists across the globe, the program pieces together how the earliest animals on Earth led to the astonishing diversity of creatures today, from simple sponges to more complex animals such as human beings. Part 1 explores the scientific evidence that points to the one single animal that gave rise to all other animals, including humans. Then it explores the group of creatures whose descendents were the first to harness the power of muscles and nerves. Part 2 explores how the first animal to develop a head, eyes and brain also pioneered a new way of survival: hunting. Next, scientists explore the first animals to conquer land and pioneer flight. Part 3 explores the offensive and defensive strategies that all creatures depend on in the great survival game of life. Finally, the program looks at the accomplishments of a group of creatures that lack heads, eyes and centralized brains.
